Abstract：Objective To compare the detection rate of white matter hyperintensities in the brain of pilots and normal humans. Methods The WMHs of 290 cases of MRI and 910 cases of normal persons were collected between January 2012 and December2014. Results There were 40 cases of WMHs among the pilots and the detection rate was 13.79%. However, there were 83 cases of WMHs among the ordinary people and the detection rate was 9.12%. Age had no effect on the incidence of WMHs. WMHS distribution was similar between the two groups, and the difference was not of statistical significance. In the group of 40 pilots with WMHs, scale scores were above 26 points by Montreal cognitive assessment. The WMHs volume of 8 pilots who had performed 6 months of consecutive flight was increased considerably, and the difference was was statistically significant. Conclusion The detection rate of WMHs is higher among the pilots than among the ordinary people, but the distribution of WMHs is similar- in the frontal lobe. Pilots' point WMHs do not affect cognition. The volume of WMHs will increase as pilots fly for a longer period of time.
